Hey colleagues how are you,
I have and issue about connecting Keycloak to roundcube.
Looks like all good button appears and redirect looks like working but after enter my creds to Keycloak he says OAuth failed see some screens
when i try this link it says internal server error http://mail.somedomain.com:8443/realms/master/protocol/openid-connect/token
